-STEAM OR GAS IVlOTORENGINE.

SPECIFICATION forming part ofI-etters Patent No, 382,008, dated May 1, 1888.

(No model.)

To aZZ whom it may concern.-

Be it known that I, BENJAMIN C. POLE, a citizen of the United States, residing at (3am-- den, in the county of Camden, State of New Jersey, have invented certain new and useful Improvements in Steam or Gas Motor Engines, of which the following is a specification, reference being had therein to the accompanying drawings. I

My invention relates to certain new and useful improvements in engines; andit consists in certain constructions whereby the engine is free and unloaded at suitable intervals, and in permitting the engine to be connected with its,

work automatically and elastically. For the purpose of attaining this point several constructions, hereinafter described, are adapted to this use.

Figure lrepresents a steam-engine provided with my improvement. Fig. 2 represents a gas-engine with myimprovement-s connected. Fig. 3 is a plan of Fig. 2. Fig. 4 is a part sectional side elevation of a device for imparting power under this invention. Fig. 5 is a modified form of Fig. 4. Fig. 6 is a front view of Fig. 5. Fig. 7 is a modified form of applying power under this invention. Fig. 8 is a part sectional front View of Fig. 7. Figs. 9 and 10 are views of different forms of rubber for providing yielding surface for this invention. Fig. 11 is an air-cylinder for elastic action of the device. Fig. 12 is a side elevation of the friction-brake, showing in broken section the form of side plates and with thefriction brake-strap removed. Fig. 13 is a side elevation of the friction-brake, showing the friction-strap in full line and its operatingarm and a piece of the side plate in section. Fig. 14 represents the sliding clutch and operating arms therefor.

Similar letters refer to similar parts.

Referring to the drawings, the crank-axle A i of the ordinary steam-engine is provided with the fly-wheel A, and keyed on the said shaft is a wheel, A to the side of which is a washer and collar, A A. Upon A is a cover, A, and this connects with a. side cover, A". This coverA is permitted to ride on a free wheel, A. On the outside of A and at its top rim,

A is a friction-brake, partly of construction as shown in Letters Patent No. 365,279, June 21, 1887. A strap, A, is tightened by the lever A This lever is forced in and out by the link A, which is connected to the sliding sleeve A". This in turn is operated by the lever A, connecting rod A and lever A to cam A on the end of shaft A. The'outer rim, A ,is made apulley-wheel connecting with the belt 13 on the pulley B, which is on the second shaft, B provided with fly-wheel B inside or outside working pulleys B 5 The operation of this invention is simply that the steam applied to thepiston of the engine surges forward at a high velocity the fly-wheel A on the crank-shaft A, and this shaft A is keyed at a to wheel AF, and is only connected to the belt B by the case A", which is also free and independent, carrying with it the strap A", the side A, the lever A the link A, and sleeve A. Upon the cam A throwingin the lever A and the connecting-rod A, lever A pushes out the sleeve A, which lifts the lever A and closes down the strap A on the top of the wheel A terposed between it and wheel A suitable rubber springs, D. The closing of this strap causes the power of the engine to be thrown elastically into the belt B on the pulley B, imparting momentum to the fiy-wheel 13 on the gine. Governors for regulating the speed of This wheel has inthe engine will be on both the shafts A and B for the purpose of unison of action.

In the instance of the gas-engine=-==a machine which takes its power only at one end of the stroke, and in some cases only at every second revolution-certain additional construction is necessary to make operative the unison action in the method of employing this invention. The cylinder E of the gas-engine is provided with the ordinary water-j acket system for the purpose of keeping the cylinder cool, and has the piston-rod E and across-head, E", the connecting-rod E and an additional connectingyoke, E, to a vibrating arm, E This arm is upon the shaft E, while the connectingrod E is upon the crank-shaft E.

On the shaft E is keyed the ratchet-Wheel E having the ratchet-pawl E The bolt of said ratchet is made to be operated by a flexible shaft, E Said flexible shaft is operated by a shaft, F, which has on the end a rising and falling crank, F. This crank is raised and lowered by a guide-bolt, F", and spring The operation of this guidebolt is by means of the sliding bar F*, having the projection F which engages with the bolt F. The connecting-rod F connects with a crank, F which is upon ashaft, F which revolves once for every two revolutions of the shaft E.

The shaft F is provided with the beveled pinion F", and on the governor is a beveled wheel, F that operates a pair of governors to open and close the gassupply valves,either in conjunction with or independently of the governor system G ofthe gas-engine, said governor system G being operated by beveled pinions of like nature to that upon shaft F these pinions operating the gas-engine well-known system of valves common to that class of engines, or, in the instance of steam, operating the cut-offs in similar way.

The vibrating arm is provided with an extension, II, and this extension is provided with a seat, H, upon which is a rubber spring, H This spring H connects with afreely-rid ing piece, H, that may be provided in someinstances with pawl E or roller H101, by vibrating the lever E with its extension Hto springs H and construction H and pawl E", or roller H,engages the wheel E ,and,according to the action desired and by the movement of flexible shaft E,engages the smooth wheel 11 which is keyed upon the shaft E", through the medium of said roller, when allowed to do so by the catch-action Hflthat is connected to flexible shaft E".

An air-cylinder, K, making a cushion, may be provided in place of the rubber H The operation of my invention is as follows: The development of power is due to the use of energical velocity given to a fly-wheel when in an unloaded condition by an engine-motor; and referring to Fig. 1 a stationary engine is provided with a crank and axle, A, and this axle is free to revolve at a speed regulated by a governor. The shaft A is provided with a cam, A that revolves with the shaft, and by the revolution of this cam, through the medium ofthe connection hereinbefore described, a friction-brake is made to attach and detach the crank and axle shaft from the cover of the said brake and belt B, which rides thereon, and through the medium of the friction-brake and the iiy-whccl, that has received the impetus from the power of the engine, the connection is made by the belt B and to the second shaft, B", and in this manner the concussion of the energical velocity to the fly-wheel B and this flywheel is regulated in its speed by a governor to check too high a speed given by the engine. The operation of the gasengine simply varies in that a rocking or vibrating arm, E is provided with the spring H with the connection H. This in turn imparts motion to the pawl E or roller H, and by either of these devices connects to the wheel H or to the ratehetwheel E whichever maybe used. The

attachment of the vibrating arm or H is regulated by the construction shown. This construction merely raises and lowers automatically certain levers with the revolution of the shaft E, upon which is the beveled wheel L intergearing into the beveled wheel L, and these in turn revolve the shaft F and crank F The connecting-rod F raises and lowers or vibrates the rod F, and this raises andlowers the arm F. This in turn moves up and down the spring F and bolt F, provided with the spring to elastically move the arm F on shaft F. This shaft F terminates in a flexible shaft, E attached to the bolt on which the pawl E is hinged. Therefore when the pawl is forced in and on the ratchet the arm E" is pushed out by the power of the engine, and the pawl E" is engaged to the wheel E, revolving the shaft E, and the attachment by the pawl E or roller II is adjusted so that the explosion or expansion which gives power to the engine-motor shall take place when the engine-motor is detached and unloaded from its work. Thus the energizer, being any kind of motive power, is unloaded, and afterward by itselfautomatically attached to the work expected to be done by the engine-energizer. The governor M raises and lowers the arm M. This in turn can be connected to thegovernor G by means of the rod M and lever M; or it may connect an electric stopyalve, M, upon the gas-pipe N, and by means of the fluid vapors for working the engine-motor the energizer may be regulated or stopped or checked in an undue speed and any power may be used.
